Quick answer: Blepharitis is inflammation at the eyelid margin. It can cause itching, flakes or “collarettes” around the lashes, burning, watery eyes, recurrent styes, and fluctuating vision. Common contributors include skin inflammation, bacteria, blocked meibomian glands, dandruff or rosacea, and Demodex mites. Warm compresses and gentle lid hygiene are useful foundations, but persistent symptoms deserve an examination because the treatment depends on the cause.
Key takeaway: Clean eyelids can reduce symptoms, but chronic or recurrent blepharitis needs a cause-based assessment of the lashes, glands, tear film and cornea.
What is blepharitis?
The eyelid margin is a busy interface: eyelashes, tiny oil glands, skin bacteria, tears and the ocular surface all meet there. Blepharitis means that this area is inflamed. It is often a chronic, relapsing condition rather than a one-time infection, so symptoms can improve and then return.
Anterior blepharitis affects the skin and lash roots at the front of the lid. Flakes, greasy scales or debris may collect at the lashes. Posterior blepharitis involves the meibomian glands, which release the oily layer that slows tear evaporation. The two patterns can occur together and can contribute to dry eye.
Why office workers in Seoul notice it
Long screen sessions reduce complete blinking, while heating and air-conditioning increase evaporation. Contact lenses, eye makeup, fine dust, and rubbing itchy eyes can further irritate the lid margin. People commuting through Guro Digital Complex or Gasan Digital Complex may notice burning and fluctuating vision by late afternoon, then crusting or sticky lashes in the morning.
Blepharitis is not the same as contagious pink eye. It usually does not spread from person to person, although an acute red eye with discharge may be a different condition. If the eye is very painful, light-sensitive or suddenly blurry, do not assume it is routine blepharitis.
Symptoms that point toward eyelid-margin disease
- Itchy, burning or gritty eyelids
- Crusts or flakes at the base of the eyelashes, especially on waking
- Red or swollen lid edges
- Watery, foamy or intermittently blurry vision
- Contact-lens discomfort that is worse later in the day
- Repeated styes or a firm eyelid lump called a chalazion
- Light sensitivity or a sensation that something is in the eye
- Loss or clumping of eyelashes in more advanced disease
Symptoms do not prove that mites are present. Demodex is more likely when there are persistent cylindrical sleeves or “collarettes” wrapped around the lash bases, particularly when standard warm compresses and cleansing have not solved the problem. The AAO’s blepharitis guideline describes collarettes as a clue that should prompt consideration of Demodex.
Blepharitis, dry eye and Demodex: how they overlap
| Pattern | Typical clues | What an exam adds |
|---|---|---|
| Anterior blepharitis | Flakes, crusts or redness around the lashes | Checks the lid margin, lash roots and skin conditions |
| Posterior blepharitis / MGD | Burning, fluctuating vision, frothy tears, recurrent styes | Assesses gland openings, oil quality and tear-film stability |
| Demodex blepharitis | Collarettes around lashes, persistent itch, recurrence after basic hygiene | Direct lash examination; mite testing may be considered in selected cases |
| Allergy or conjunctivitis | Prominent itch, watery or stringy discharge, red conjunctiva | Looks for surface inflammation and rules out corneal involvement |
These categories overlap. A person can have Demodex, meibomian-gland dysfunction and allergy at the same time. That is why a single bottle of artificial tears may soothe symptoms without fixing the eyelid inflammation.
How an ophthalmologist diagnoses the cause
- History. We ask about morning crusting, itch, contact lenses, makeup, skin disease, dandruff, rosacea, medicines and previous treatments.
- Magnified lid examination. A slit lamp shows lash collarettes, blocked gland openings, abnormal oils, lid-edge inflammation and tiny corneal changes that a mirror cannot show.
- Tear-film and corneal assessment. Break-up time, staining and the tear meniscus help show whether blepharitis is destabilising the surface and vision.
- Targeted gland assessment. Expression or meibography may be useful when MGD is suspected. The result can guide warm compresses, in-office gland treatment or dry-eye therapy.
- Demodex assessment when indicated. The pattern of collarettes often provides the clue. A doctor may examine lashes directly or use a targeted test; not every patient needs lash epilation.
Bring your eye drops, contact-lens case and a list of skin or allergy medicines. If you have old photos showing recurrent swelling or styes, they can help explain the pattern.
Treatment options and their limits
| Option | May be appropriate for | Important limits or risks |
|---|---|---|
| Warm compress and gentle lid cleansing | Most mild anterior or posterior blepharitis | Needs consistent technique; very hot water or forceful rubbing can injure skin or cornea |
| Preservative-free artificial tears | Dryness and fluctuating blur from an unstable tear film | Relieves symptoms but does not remove collarettes or unblock glands |
| Prescription antibiotic or anti-inflammatory treatment | Selected bacterial, inflammatory or rosacea-associated disease | Must be prescribed and monitored; steroid drops can raise eye pressure or worsen infection if misused |
| Gland-focused treatment, including in-office options | Persistent MGD when home care is insufficient | Benefit varies; maintenance and surface care remain important |
| Lotilaner ophthalmic solution 0.25% | Demodex blepharitis where the medicine is approved and available | U.S. FDA indication is specific to Demodex blepharitis; Korean availability, prescribing and cost require local confirmation |
What the FDA approval does—and does not—say about lotilaner
In the United States, the FDA label states that XDEMVY (lotilaner ophthalmic solution) 0.25% is an ectoparasiticide indicated for the treatment of Demodex blepharitis. The approved regimen is one drop in each affected eye twice daily for six weeks. FDA approval is based on specific clinical trials and a specific diagnosis; it does not mean the medicine treats every form of blepharitis, dry eye or eyelid redness. The label lists eye irritation and other ocular adverse reactions, and the product may not be available or approved in the same way in Korea. A Korean ophthalmologist should confirm the diagnosis and local prescribing pathway.
Two randomized vehicle-controlled trials enrolled 833 patients in total for the U.S. approval program. Those results support the medicine’s indication, but they do not guarantee the same response for every patient, and they do not replace eyelid hygiene or treatment of coexisting MGD.
Safe eyelid care at home
- Wash your hands before touching the eyelids or lenses.
- Use a clean warm compress over closed eyes. Warm should feel comfortable, never hot enough to burn.
- After the compress, gently clean the lash line with a commercially prepared lid wipe or the method your clinician recommends.
- Do not squeeze a stye or scrub hard enough to make the skin sore.
- Pause eye makeup and contact lenses during a flare, and replace old mascara or eyeliner.
- Keep towels, pillowcases and lens supplies clean. Do not share eye makeup or eye drops.
Tea bags, undiluted essential oils and homemade mixtures are not automatically safer. Tea-tree products can irritate the ocular surface, and essential oils should never be placed in the eye. If you have reduced dexterity, recent surgery or significant inflammation, ask for a demonstrated technique before performing lid massage.
When blepharitis needs prompt or urgent care
Arrange a prompt eye examination for symptoms that persist despite several weeks of careful hygiene, repeated chalazia, new lash loss, a unilateral lesion, or worsening contact-lens intolerance.
Seek same-day care for severe pain, marked light sensitivity, a red eye with reduced vision, a corneal white spot, sudden vision loss, chemical exposure, or halos with nausea or vomiting. Those signs can indicate keratitis, uveitis, acute pressure rise or another problem that needs more than lid cleaning.
Frequently asked questions
Is blepharitis contagious?
Most chronic blepharitis is not contagious. A sudden red eye with discharge may be viral or bacterial conjunctivitis instead, so avoid sharing towels and arrange an examination if the pattern is new.
Are Demodex mites the same as an infection?
Demodex mites are microscopic organisms that can live in follicles and glands. Their presence alone does not prove disease; the diagnosis depends on the lash findings, inflammation and symptoms.
Can blepharitis cause blurry vision?
Yes. Oil-gland dysfunction can destabilise the tear film, causing blur that changes after blinking. Persistent or one-sided blur needs an eye examination because cataract, corneal disease or retinal disease can look similar.
How long does lid hygiene take to work?
Some people feel relief within days, but chronic blepharitis often needs several weeks of consistent care. If the lid margin remains inflamed, the next step is to reassess the diagnosis and look for MGD, allergy, rosacea or Demodex.
Can I wear contact lenses with blepharitis?
It depends on the surface and severity. Remove lenses if the eye is painful, red, light-sensitive or blurry, and do not reinsert them until a clinician says it is safe. Bring the lenses and case to the visit when infection is a concern.
Does everyone with collarettes need XDEMVY?
No. Collarettes suggest Demodex, but treatment still depends on the examination, local availability and other eyelid disease. U.S. FDA approval is specific to Demodex blepharitis, not a blanket approval for every crusty eyelid.
Can I book an English consultation in Guro?
Yes. Dr. Daniel Jinhag Baik is a Korean-American ophthalmologist fluent in English and Korean. Nunehim Eye Center serves patients from Guro, Gasan, Geumcheon, Yeongdeungpo, Dongjak, Sillim, Sindaebang and Gwanak.
Dr. Baik’s practical perspective
When a patient says “my eyes are dry,” I also look at the eyelid margin. Blocked glands, collarettes or chronic lid inflammation can keep the tear film unstable even when artificial tears are used regularly. The goal is to identify which part of the eyelid–tear-film system is failing, then choose the least burdensome treatment that addresses that cause.
